Hi folks, I have had to send my first Surface Pro 3 i7 256 back for what I thought was over heating and now the refurbished replacement I was given is doing pretty much the same, getting up to 55C and the fan kicks in and stays on with nothing running(including background tasks) other than IE and this website and CPU usage not going over 2%. I'm not talking about the whisper quiet fan you can only hear when you put your ear next to the grill. it's the next stage(s) up from that when you can hear it quite clearly from a metre away. The only reason I'm thinking this isn't right is because a couple of days ago I was browsing away for well over an hour using chrome and IE with multiple tabs and the fan didn't kick in once with the temp staying below 55C. Perfect I thought, that last firmware update fixed it and I can really use this device as my laptop replacement as Microsoft has advertised. Do I have another faulty device or this is just how it is, am I expecting too much for it to be quiet when doing very light tasks? When does your fan kick in? Don't get me wrong I really like the SP3 but it's pretty embarrassing sitting in a meeting with this thing and the fan going off when it's not even doing anything.
